Ace Powder Guides has been taking riders into the backcountry of West Yellowstone for over 15 years. APG is permitted with the Gallatin and Beaverhead-Deerlodge National Forests. All our guides are avalanche 2 certified, avalanche 1 instructors for the Gallatin Avalanche Center and members of the WYSAR back country team. We provide every client with proper avalanche gear for all back country trips along with a short session of education on the gear. Ace Powder Guides is the only Back Country guide service and snowmobile rental in West Yellowstone. Give us a call anytime for snow conditions, sled and avalanche gear rentals, lodging or a backcountry trip. Here is a few pics of some of the areas we ride.
